Urban lighting is a general term for urban functional lighting and landscape lighting. It plays an important role in ensuring urban security, improving urban functions, and improving living environment. The “Regulations on Urban Lighting Managementâ€, which was implemented by the state on July 1, 2010, stipulates that the competent department of urban lighting shall strictly control the scope, brightness and energy density of landscape lighting according to urban lighting planning, and shall be phased out in full according to relevant state regulations. Inefficient lighting products. Under the leadership of the higher authorities, Yueyang City's urban lighting industry has not only emphasized its functionality, but also paid attention to economic benefits. It has gradually embarked on the development track of legalization, standardization and scientificization.
Yueyang City Lighting Development Status
At present, there are a total of 11,714 street lamps in the urban area of ​​Yueyang City, and 32,126 landscape lights. Functional lighting 100% covers the main secondary roads and small streets and alleys in the urban built-up area, basically eliminating the phenomenon of no lights and no lights, maintenance management measures in place, repairing black lights within 24 hours, lighting all year round The rate is maintained above 98%. The urban lighting facilities in the urban area are remotely monitored and opened by the monitoring center located in the street lighting management office of Yueyang City. Through the construction and upgrading of the landscape lighting of overpasses, parks, green spaces and buildings, the night viewing band has been formed, providing the public with a comfortable urban night environment, providing the city with a platform to show itself.
In the management system, Yueyang City Administration is the administrative department of urban lighting, and Yueyang City Street Lamp Management Office is responsible for the construction, operation and maintenance of urban lighting facilities.
Measures to strengthen urban lighting management
In the battle for urban tug-of-war, urban lighting work has directly affected the quality of a city's hard environment. Yueyang City Street Light Management Office increased management efforts to correctly develop urban lighting. Always adhere to the scientific development concept as the leader, strictly manage according to law, based on scientific development. Mainly did the following work:
I. Actively prepare for the preparation of special plans for urban lighting to promote the development of urban lighting science and regulation
To guide the development of urban lighting science and regulation in our city, we must adhere to the principle of people-oriented, highlighting key points, ensuring functions, economical and practical, saving energy, and protecting the environment. Yueyang City Management Bureau and City Street Lights Department are actively preparing for the preparation of "Special Plan for Urban Lighting". Work, according to the actual needs of urban development, the preparation of the special plan for urban lighting in Yueyang City will be incorporated into the overall urban planning. Strive to make the city's urban lighting to achieve reasonable layout, primary and secondary considerations, focus, distinctive features, clear energy-saving indicators and measures to guide the city's urban lighting to efficient, energy-saving, environmentally friendly, healthy development.
Second, improve the management mechanism and improve the institutional system
Formulate and improve various management systems and centrally exercise management functions. The work responsibilities will be implemented to the people, and the maintenance management tasks will be decomposed into two maintenance engineering teams and lighting management offices and signed maintenance contract, strictly in the design, construction, supervision, completion, maintenance and other aspects.
Improve the urban lighting system and assessment system. Formulate the system of urban lighting design review, completion acceptance, construction site management, maintenance quality management, external power supply, etc., and issue relevant supporting management rules. Improve the urban lighting assessment system, formulate detailed rules for street lighting assessment, and enhance the operability of urban lighting facilities maintenance standards. Combined with the evaluation system of urban standardization management of Yueyang City, dynamic management and collaborative management of urban lighting facilities, establishment of daily communication channels and information exchange system, improvement of the working mechanism of linkage coordination, and jointly solve problems in the development of urban lighting.
Third, implement landscape lighting upgrade project to add color to the urban night scene
In the past three years, with the great attention of the municipal party committee and the municipal government, the city gradually implemented the landscape lighting upgrade project, expanded the installation scope of the landscape lights of the central city building, and formed the landscape features of the main street of the city, “one street and one sceneâ€. It has upgraded the public landscape lighting grades of Jinluo Park, Lake Scenic Belt and Baling Square, and beautified the night view of Yueyang. In the process of upgrading the urban landscape lighting, we eliminated the original high-energy, low-efficiency lighting products and switched to energy-saving products. At present, all landscape lighting uses LED lamps to achieve the goal of beautifying the city and saving energy.
Fourth, deepen the concept of energy saving and emission reduction, and promote the development of green lighting
Extensively carry out urban green lighting engineering activities and strive to reduce power consumption. In order to save energy, protect the environment, and promote health, in accordance with the relevant standards of the Ministry of Construction on green lighting, we will actively promote green lighting, improve the quality of urban lighting, and strive to improve the urban living environment. The specific measures are as follows:
1, using high efficiency lamps
The efficiency of the luminaire is an important indicator to measure the light utilization rate of the luminaire. Taking the 400 watt sodium lamp as an example, assuming that the luminaire efficiency is increased from 60% to 75%, the electricity cost can be saved by 0.42 yuan per day. At present, the products of imported or joint venture backbone enterprises are basically used in the main streets of Yueyang, and the efficiency of lamps is generally above 75%.
2, using efficient light source
The earliest light source used incandescent lamps, his luminous efficiency was only a few lm per watt. By the 1970s, high-pressure mercury lamps appeared, and the luminous efficiency reached more than 30 lm per watt. We call it the second-generation light source. The sodium lamp is called the third generation light source, and its luminous efficiency reaches 100-150 lm per watt. Before 2005, some parts of Yueyang still had mercury lamps and incandescent lamps. After 2005, incandescent lamps were completely eliminated, and high-pressure mercury lamps basically disappeared. At present, there are no inefficient lighting products in urban road lighting and landscape lighting projects in our city, and the high-efficiency and low-energy high-pressure sodium lamps recommended by the Ministry of Construction have been basically popularized. This allows us to consume the same amount of electricity, but it greatly improves the illumination of the road. At present, there is a new type of light source LED lighting. In just a few years, people have improved his luminous efficiency from 5-10 lm per watt to more than 60 lm per watt. It is estimated that it will reach 200 lm per watt in the future. A very promising source of light. In the transformation of Yueyang Avenue Dayan landscape lights implemented in September 2010, the city adopted a new type of 20W LED lamps, a total of 234 sets; in the renovation of Luyuan West Road in Yueyang City, 80W LED lights were used, totaling 41 sets, which satisfied The requirements for road lighting are avoided, and light pollution and energy waste are avoided.
3, change the control method
The combination of light control and time control is adopted to adjust the switching time of the street lamp at any time according to the changes of the season and the weather, so as to make the switch light reasonably. The midnight light-saving mode is adopted for different road sections, that is, the street lights of the street or the urban-rural junction street with higher illumination in the opposite position, in the latter half of the night, when the traffic volume and traffic volume are small and the illumination does not need to be too high, 23: After 00, some lights are extinguished to save energy. The characteristics are: small investment, quick effect, obvious effect, simple and easy method, easy maintenance. The biggest disadvantage is that the illumination is uneven and can not solve the voltage bias in the middle of the night. High and affects the life of the light source.
4, single lamp compensation combined with centralized compensation
With the technological advancement of urban road lighting and the enhancement of energy-saving awareness, high-pressure gas discharge lamps such as high-pressure high-pressure nano lamps and metal halide lamps with high luminous efficiency and long service life have gradually become mainstream. However, due to the low power factor of such a light source, generally between 0.3 and 0.5, the power factor requirement of the power distribution system to the power distribution system (the power factor of the low voltage power supply side of the low voltage power supply should be above 0.9, and the low voltage of the high voltage power supply) The power side power factor should be 0.95). There is a big gap. Therefore, the road lighting electrical system with the gas discharge lamp source installed should be equipped with power factor compensation equipment to implement single lamp compensation or centralized compensation.
When the city specifically selects the compensation plan, it determines the appropriate compensation method according to the site conditions. The centralized compensation technology scheme is adopted for the urban road lighting electrical system that has been put into operation, which can reduce the installation workload and the maintenance workload. When the three-phase load current of the street lamp is basically symmetrical, the three-phase co-compensation centralized compensation means is used to improve the line power factor. When the three-phase load current of the street lamp is asymmetric, a hybrid compensation technical solution is adopted to achieve the expected compensation target. . A single-lamp compensation technical solution is adopted for the construction of the road lighting electrical system in the design and the new construction to achieve true “local compensation†to achieve the best compensation effect.
Problem
1. The urban lighting special plan has not yet been introduced.
2. The industry management system has not been perfected.
In the city's road lighting, there is an unreasonable phenomenon of multiple management units in the industry (only one in large and medium-sized cities), resulting in overlapping organizations and waste of resources. In order to strengthen the management of the street lamp industry, improve the quality of public services, and make full use of scientific management tools such as monitoring telemetry. I hope that the street lights will be "one in the same city" as soon as possible.
